Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111130, here are decompositions:

3 + 111127 = 111130
11 + 111119 = 111130
101 + 111029 = 111130
179 + 110951 = 111130
191 + 110939 = 111130
197 + 110933 = 111130
251 + 110879 = 111130
281 + 110849 = 111130

Showing the first eight; more decompositions exist.
